氢光谱的数字CCD成像与分析方法研究

Research on digital imaging and analysis method of hydrogen spectrum

用数码成像技术对现有棱镜摄谱仪进行改造,并用计算机程序处理图谱:改造后的装置能够清晰地拍摄到氢光谱和氦光谱,在Windows画图软件或Photoshop软件中可用内插法对两者进行比较测量,或者将图像放大打印在纸上用毫米尺直接进行测量,其图像直观,计算方便,可应用于物理实验教学中.

Using the technology of digital camera, the spectrograph is improved and the spectrum is processed using computer program. The improved equipment can shoot hydrogen spectrum and helium spectrum clearly, and the two kinds of spectra are compared and measured using Windows plotting software and Photoshop software with interpolation algorithm, or enlarged and printed on paper before measured with millimeter ruler directly. This method is straightforward and easy to implement and can be applied to the teaching of physics experiments.
